Ok, so I got home this evening to find a new 2013 Obsession Knightmare waiting for me. So, I slapped a whisker biscuit on it (just because it was handy and quick to install), tied a d-loop, and did some checking and shooting. Here is what I found/think about the bow. Finish- The bow is predator camo, and looks great. The finish on this bow is flawless! Although I'm not a finish guru or chemist, I can't find a blemish anywhere. It looks fantastic.
Specs- This bow is a 55-65 lbs model, and it maxed out at 68 lbs. I measured the ata length at 33-1/2" on the nose, and the brace height came in at 6-1/4". It has a 28-1/2" module on the bow and actually measures 28-3/4". Feel- I like a bow that balances well, and this bow does just that. The bow just sits in your hand, like last years models. Possibly the biggest improvement on this bow vs last years models, is the grip. The grip on this bow was made for me! They did a great job of listening to the feedback about the grip on last years bow and as far as I'm concerned, they hit the nail on the head this year. I'll get into the draw cycle shortly.
Tuning/Speed- Ok, here's the good stuff. Right out of the box the cams were perfectly synched, so after installing the rest and d-loop I went straight to shooting. The draw cycle is very good on the bow, especially for the speeds that it is putting out. I will say that it felt like it ramped up quickly, and later when I did a DFC it showed this. Overall though, I thought the draw cylce was very nice, and as with most binary cam bows this one has a very nice valley and high letoff %.
On the shot it is just dead. If you shot last years bows, this one is more of the same. Extremely quiet, and absolutely dead on the shot. I initially set the biscuit at around 7/8" from the riser, and set the nock point at 1/8" high. I grabbed a couple of Carbon Express Mach 5 350's and got the paper rack out. I shot a couple of arrows and it showed a slight left tear, which is exactly what I was hoping for. I bumped the rest in towards the riser to right around 13/16" (25/32" to be exact haha) and shot a perfect bullet hole! I backed up and shot another perfect bullet hole! As most of us know, last years bows required shimming to get the bows to tune closer to center, but this year they seem to be right on the money with a properly spined arrow. Another improvement by OA.

So, I got the chronograph and the light kit out for some speed testing. As said earlier, the draw length is measuring 1/4" long so it is at 28-3/4", and it is pulling 68 lbs. I shot 3 different arrow weights, and here are the numbers.
Arrow 1- 442 grains- 293.3, 293.7, 294
Arrow 2- 381 grains- 312.7, 313.6, 313.6
Arrow 3- 345 grains- 327.8, 327.4, 328.4
Knightmare Chrono Reading.jpg At 28.75" dl, and 68 lbs, with only 6 grains on the string, On Target 2 IBO's this bow at 349 fps! OT2 though seems a little fast, so I ran the numbers on Backcountry IBO calculator as well, and it IBO's the bow at 345 fps. Any way you slice it, the bow is fast. And remember, these numbers are RIGHT OUT OF THE BOX.
My Easton Bow Force Mapper is out of commision at the moment, but I did a little DFC the old fashioned way with a vertical draw board on my Bow-A-Constrictor, a hanging scale, and a piece of graph paper. I marked the poundage at every 1" interval which I know isn't as accurate as the mapper, but still works. You'll notice that the bow builds fairly quickly and hits peak weight between 5"-6" into the draw cycle. But here is where I think you could eek a little bit more speed out of it. It only holds peak weight for about 3" at the front of the draw cycle, and then slowly drops about 3 lbs and sort of plateau's again for about 3" before dropping off into the valley. When I get some time I'll see about trying to get this thing to hold peak weight longer and flatten out the DFC.
I believe that Obsession Archery has definitely listened to it's customers and made improvements in every area that there were complaints. I forgot to mention the fact that I ordered this bow on Thursday December 6th, and recieved it today December 11th. Grip, speed, tuning, shipping times, etc seem to have all been improved. Go try the new Obsession Bows.
